All-Star Orchestra is an orchestral music project created by Gerard Schwarz, former music director and conductor laureate of Seattle Symphony. It is a television and DVD project, filmed by 18 high definition video cameras without an audience for PBS, the Khan Academy, educators, students, "and enthusiasts." Mr Schwarz assembled 95 leading orchestral musicians, of major symphony orchestras, from across the United States. The assembled players performed over a four-day period. In 2014, the program consisted of eight episodes. The second season began broadcast in the fall of 2015. The organization's web site provides details of the second season's programs. wikipedia
